While providing ESD protection with transient voltage suppression (TVS) diodes, the TVS protection adds little or no additional glitch in the high-speed differential signals. The high-speed transition minimized differential signaling (TMDS) ESD protection lines add only 0.8-pF capacitance. 1 • • • • • • • • IEC 61000-4-2 Level 4 ESD Protection – ±8-kV Contact Discharge on External Lines Single-Chip ESD Solution for HDMI Driver On-Chip Current Regulator with 55-mA Current Output Supports All HDMI 1.3 and HDMI 1.4b Data Rates (–3 dB Frequency > 3 GHz) 0.8-pF Capacitance for the High Speed TMDS Lines 0.05-pF Matching Capacitance Between the Differential Signal Pair 38-Pin TSSOP Provides Seamless Layout Option with HDMI Connector Backdrive Protection – TMDS_D[2:0]+/– – TMDS_CK+/– – CE_REMOTE_OUT – DDC_DAT_OUT – DDC_CLK_OUT – HOTPLUG_DET_OUT Lead-Free Package The low-speed control lines offer voltage-level shifting to eliminate the need for an external voltage levelshifter IC. The control line TVS diodes add 3.5-pF capacitance to the control lines. The 38-pin DBT package offers a seamless layout routing option to eliminate the routing glitch for the differential signal pairs. The DBT package pitch (0.5 mm) matches with the HDMI connector pitch. In addition, the pin mapping follows the same order as the HDMI connector pin mapping. The TPD12S521 provides an on-chip current limiting switch with output ratings of 55 mA at pin 38. This enables HDMI receiver detection even when the receiver device is powered off.

In many cases the core ICs, such as the scalar chipset, may not have robust ESD cells to sustain system-level ESD strikes. In these cases, the TPD12S521 provides the desired system-level ESD protection, such as the IEC61000-4-2 (Level 4) ESD, by absorbing the energy associated with the ESD strike. While providing the ESD protection, the TPD12S521 adds little or no additional glitch in the high-speed differential signals (see Figure 5 and Figure 6). The high-speed TMDS lines add only 0.8-pF capacitance to the lines. In addition, the monolithic integrated circuit technology ensures that there is excellent matching between the two-signal pair of the differential line. This is a direct advantage over discrete ESD clamp solutions where variations between two different ESD clamps may significantly degrade the differential signal quality. The low-speed control lines offer voltage-level shifting to eliminate the need for an external voltage level-shifter IC. The control line ESD clamps add 3.5-pF capacitance to the control lines. The 38-pin DBT package offers a seamless layout routing option to eliminate the routing glitch for the differential signal pairs. The TPD12S521 provides an on-chip regulator with current output ratings of 55 mA at pin 38. This current enables HDMI receiver detection even when the receiver device is powered off. DBT package pitch (0.5 mm) matches with HDMI connector pitch. In addition, pin mapping follows the same order as the HDMI connector pin mapping. 8.2 Functional Block Diagram ESD_BYP 5V_SUPPLY TMDS_D2+ TMDS_D1+ TMDS_D0+ TMDS_CK+ TMDS_GND TMDS_GND TMDS_GND TMDS_GND TMDS_D2– TMDS_D1– TMDS_D0– TMDS_CK– LV Supply CE_REMOTE_IN LV Supply CE_REMOTE_OUT LV Supply DDC_CLK_IN DDC_DAT_OUT DDC_DAT_IN LV Supply DDC_CLK_OUT 5V_SUPPLY HOTPLUG_DET_OUT HOTPLUG_DET_IN 55-mA Overcurrent Switch 5V_OUT Submit Documentation Feedback Copyright © 2007–2016, Texas Instruments Incorporated Product Folder Links: TPD12S521 7 TPD12S521 SLVS639F – OCTOBER 2007 – REVISED FEBRUARY 2016 www.ti.com 8.3 Feature Description 8.3.1 Single-Chip ESD Solution for HDMI Driver TPD12S521 provides a complete ESD protection scheme for an HDMI 1.4 compliant port. The monolithic integrated circuit technology ensures that there is excellent matching between the two-signal pair of the differential line. This is a direct advantage over discrete ESD clamp solutions where variations between two different ESD clamps may significantly degrade the differential signal quality. The 38-pin DBT package offers a seamless layout routing option to eliminate the routing glitch for the differential signal pair. 8.3.2 Supports All HDMI 1.3 and HDMI 1.4b Data Rates The high-speed TMDS pins of the TPD12S521 add only 0.8 pF of capacitance to the TMDS lines. Excellent intrapair capacitance matching of 0.05 pF provides ultra low intra-pair skew. Insertion loss -3 dB point > 3 GHz provides enough bandwidth to pass all HDMI 1.4b TMDS data rates. 8.3.3 Integrated Level Shifting for the Control Lines The low-speed control lines offer voltage-level shifting to eliminate the need for an external voltage level-shifter IC. The control line ESD clamps add 3.5-pF capacitance to the control lines. 8.3.4 ±8-kV Contact ESD Protection on External Lines In many cases, the core ICs, such as the scalar chipset, may not have robust ESD cells to sustain system-level ESD strikes. In these cases, the TPD12S521 provides the desired system-level ESD protection, such as the the IEC61000-4-2 (Level 4) ESD, by absorbing the energy associated with the ESD strike. 8.3.5 38-Pin TSSOP Provides Seamless Layout Option With HDMI Connector The 38-pin DBT package offers seamless layout routing option to eliminate the routing glitch for the differential signal pair. DBT package pitch (0.5 mm) matches with HDMI connector pitch. In addition, pin mapping follows the same order as the HDMI connector pin mapping. This HDMI receiver port protection and interface device is specifically designed for next-generation HDMI transmitter protection. 8.3.6 Backdrive Protection Backdrive protection is offered on the following pins: TMDS_D[2:0]+/–, TMDS_CK+/–, CE_REMOTE_OUT, DDC_DAT_OUT, DDC_CLK_OUT, HOTPLUG_DET_OUT. 8.3.7 Lead-Free Package Lead-Free Package for RoHS Compliance. 8.3.8 On-Chip Current Regulator With 55-mA Current Output The TPD12S521 provides an on-chip regulator with current output ratings of 55 mA at pin 38. This current enables HDMI receiver detection even when the receiver device is powered off. 8.4 Device Functional Modes TPD12S521 is active with the conditions in the Recommended Operating Conditions met. The bi-directional voltage-level translators provide non-inverting level shifting from VLV on the system side to either 5V (for SDA , SCL, HPD), or 3.3 V (for CEC) on the connector side. Each connector side pin has an ESD clamp that triggers when voltages are above VBR or below the lower diode's Vf. During ESD events, voltages as high as ±8-kV (contact ESD) can be directed to ground via the internal diode network. Once the voltages on the protected line fall below these trigger levels (usually within 10's of nano-seconds), these pins revert to a non-conductive state. 8 Submit Documentation Feedback Copyright © 2007–2016, Texas Instruments Incorporated Product Folder Links: TPD12S521 TPD12S521 www.ti.com SLVS639F – OCTOBER 2007 – REVISED FEBRUARY 2016 9 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information TPD12S521 provides IEC61000-4-2 Level 4 Contact ESD rating to the HDMI 1.4 transmitter port. Integrated voltage-level shifting reduces the board space needed to implement the control lines. 9.2 Typical Application Refer to Figure 2 for a typical schematic for an HDMI 1.4 transmitter port protected with TPD12S521. The eight TMDS data lines (D2+/-, D1+/-, D0+/-, CLK+/-) each have two pins on TPD12S521 to connect to. The TMDS data lines flow through their respective pin pairs, attaching to the passive ESD protection circuitry. To block reverse current to the 3.3-V logic power rail, connect CEC_OUT to the 3.3-V logic level with a 27-kΩ pull-up resistor in series with a Schottky diode.

HDMI 1.65Gbps Eye Diagram With TPD12S521 on a Test Board Figure 4. HDMI 1.65Gbps Eye Diagram Without TPD12S521 on a Test Board Figure 5. Test Board to Measure Eye Diagram for the TPD12S521 (Refer to Eye Diagram Plot) 10 Power Supply Recommendations The designer needs to consider the requirement for the HDMI Transmitters Hot Plug Detect (HPD) scheme. If it is a requirement, then the VIH of HPD on the core scalar chip is the minimum voltage needed to detect a Hot Plug event. The minimum voltage requirement is V5V_SUPPLY — VDROP_MAX — VDROP_SYSTEM — VON_MAX > VIH ⇒ V5V_SUPPLY > VIH + VDROP_MAX + VDROP_SYSTEM + VON_MAX ; where VDROP_MAX is the maximum voltage drop across TPD12S521's current limiter, VDROP_SYSTEM is the voltage drop across the path from Pin 38 of TPD12S521 through the sink and back to Pin 20, and VON_MAX is the maximum voltage drop across TPD12S521's level shifting NFET when ON. Otherwise, TPD12S521 is a passive ESD protection device and there is no need to power it. 10 Submit Documentation Feedback Copyright © 2007–2016, Texas Instruments Incorporated Product Folder Links: TPD12S521 TPD12S521 www.ti.com SLVS639F – OCTOBER 2007 – REVISED FEBRUARY 2016 11 Layout 11.1 Layout Guidelines • • • The optimum placement is as close to the connector as possible. – EMI during an ESD event can couple from the trace being struck to other nearby unprotected traces, resulting in early system failures. – The PCB designer needs to minimize the possibility of EMI coupling by keeping any unprotected traces away from the protected traces which are between the TVS and the connector. Route the protected traces as straight as possible. Eliminate any sharp corners on the protected traces between the TVS and the connector by using rounded corners with the largest radii possible. – Electric fields tend to build up on corners, increasing EMI coupling. 11.2 Layout Example HDMI Connector 1 TPD12S521 Legend VIA to GND Plane VIA to 5V Plane VIA to 3.3V Plane VIA to LV Plane Pin to GND Use external and internal ground planes and stitch them together with VIAs as close to the GND pins of TPD12S521 as possible. This allows for a low impedance path to ground so that the device can properly dissipate an ESD event.
